The graceful wooden windmills—a national symbol like wooden shoes and tulips—that have broken up the flatDutch landscape for centuries yielded long ago to ungainly metal-pole turbines. Now, windmills are breaking into a new frontier. Though still in its teething stages, the "urban turbine" is a high-tech windmill designed to generate energy from the rooftops of busy cities. Lighter, quieter, and often more efficient than rural counterparts, they take advantage of the extreme turbulence and rapid shills in direction that characterize urban wind patterns. Prototypes have been successfully tested in severalDutch cities, and the city government in the Hague has recently agreed to begin a large-scale deployment in 2003.Current models cost US$8, 000 to US$12, 000 and can generate between 3,000 and 7,000 kilowatt hours of electricity per year.A、typicalDutch household uses 3,500 kilowatt hours per year, while in the United States, this figure jumps to around 10, 000 kilowatt hours. But so far, they are being designed more for public or commercial buildings than for private homes. The smallest of the current models weighs roughly 200 kilograms and can be installed on a roof in a few hours without using a crane. Germany, Finland andDenmark have also been experimenting with the technology, but the ever-practicalDutch are natural pioneers in urban wind power mainly because of the lack of space. The Netherlands, with 16 million people crowded into a country twice the size of Slovenia, is the most densely populated inEurope. Problems remain, however, such as public safety concerns, and so strict standards should be applied to any potential manufacturers. Vibrations are the main problem in skyscraper-high turbines. People don’t know what it would be like to work there, in an office next to one of the big turbines. It might be too hectiC、 Meanwhile, projects are under way to use minimills to generate power for lifeboats, streetlights, and portable generators. "I think the thing about wind power is that you can use it in a whole range of situations," saidCorin Millais, of theEuropean WindEnergyAssociation. "It’s a very local technology, and you can use it right in your backyarD、I don’t think anybody wants a nuclear power plant in their backyarD、" |

There are so many bad things about women drivers, I don’t know where to start. I guess I will get the bail rolling by talking about one of my biggest pet peeves. Why do women have to wait until they are in the car and barreling down the highway at sixty miles an hour before they decide it is time to put on their makeup Is there a law that I don’t know about that says women have to do their makeup in the car because the bathroom isn’t good enough for them I don’t know if anyone has ever informed women, but the mirror in the car is not a makeup mirror. The mirror is used for looking at other cars and pedestrians. So please do us all a favor and do your makeup before you leave the house. The next order of business for the men should be to find out whose brilliant idea it was for women to have a phone in the car. This has disaster written all over it.Everyone knows that women can’t even walk and chew gum at the same time, so how in the hell are they going to drive and talk on the phone Why is it that every time you are sitting at a red light the woman in front of you thinks this is a good time to make a phone call "HELLO LADY. THE、LIGHT IS GREEN, GET OFF THE、PHONE、AND、GO!" I really think we need to outlaw women using their cell phones while they drive. Another accident waiting to happen is when you get two women in the same car together. How many times have you seen two women just yakking away and the driver isn’t paying attention to where she is going There is either one of two things that happens when two women get in the car together. One. The women are talking and the driver doesn’t see the stop sign in front of her, so she runs it. Two: The two women are talking and at the last minute the driver realizes there is her turn, so she stops really quick in front of you and you almost rear-end her. So women please pay more attention to your driving and, for the love of God, use your turn signals--they aren’t there for decoration. I know all women out there are yelling at me and saying, "Women are better drivers than guys." If women were better drivers than men, why do guys drive on dates Why don’t women ever tell the guy, I will come pick you up Why are almost all truck drivers guys Why is it when a woman is going to move and she rents a U-Haul van, she alwaysCalls a guy to drive it for her When was the last time you watched a woman win the Indy 500 orDaytona 500All of these questions .just go to prove why guys are the kings of the roaD、 |

Ask anAmerican schoolchild what he or she is learning in school these days and you might even get a reply, provided you ask it in Spanish, but don’t bother, here’s the answer:Americans nowadays are not learning any of the things that we learned in our day, like reading and writing.Apparently these are considered fusty old subjects, invented by white males to oppress women and minorities. What are they learning In a Vermont college town I found the answer sitting in a toy store book rack, next to typical kids’ books like "Heather Has Two Mommies andDaddy is ’Disfunctional’". It’s a teacher’s guide called "Happy ToBe Me", subtitled "Building Self-Esteem". Self-esteem, as it turns out, is a big subject inAmerican classrooms. ManyAmerican schools see building it as important as teaching reading and writing. They call it "whole language" teaching, borrowing terminology from the granola people to compete in the education marketplace. No one ever spent a moment building my self-esteem when I was in school. In fact, from the day I first stepped inside a classroom my self-esteem was one big demolition site.All that mattered was "the subject", be it geography, history, or mathematics. I was praised when I remembered that "near", "fit", "friendly", "pleasing", "like" and their opposites took the dative case in Latin. I was reviled when I forgot what a cosine was good for. Generally, I lived my school years beneath a torrent of castigation so consistent I eventually ceased to hear it as people who live near the sea eventually stop hearing the waves. Schools have changeD、Reviling is out, for one thing. More important, subjects have changeD、 Whereas I learnedEnglish, modern kids learn something called "language skills". Whereas I learned writing, modern kids learn something called "communication".Communication, the book tells us, is seven per cent words, twenty three per cent facial expression, twenty per cent tone of voice, and fifty per cent body language. So this column, with its carefully chosen words, would earn at most a grade of seven per cent. That is, if the school even gave out something as oppressive and demanding as grades. The result is that, in place ofEnglish classes,American children are getting a course in "How to Win Friends and Influence People".Consider the new attitude toward journal writing. I remember one high schoolEnglish class when we were required to keep a journal. The idea was to emulate those great writers who confided in diaries, searching their soul and honing their critical thinking on paper. "Happy ToBe Me" states that journals are a great way for students to get in touch with their feelings. Tell students they can write one sentence or a whole page. Reassure them that no one, not even you, will read what they write.After the unit, hopefully all students will be feeling good about themselves and will want to share some of their entries with the class. There was a time when no self-respecting book forEnglish teachers would use "great" or "hopefully" that way. Moreover, back then the purpose ofEnglish courses (an antique term for "Unit") was not to help students "feel good about themselves", which is good because all that reviling didn’t make me feel particularly good about anything. |

One of the many theories about alcoholism is the learning and reinforcement theory, which explains alcoholism by considering alcohol ingestion as a reflex response to some stimulus and as a way to reduce an inner drive state such as fear or anxiety.Characterizing life situations in terms of approach and avoidance, this theory holds that persons tend to be drawn to pleasant situations or repelled by unpleasant ones. In the latter case, alcohol ingestion is said to reduce the tension or feelings of unpleasantness and to replace them with the feeling of euphoria generally observed in most persons after they have consumed one or more drinks. Some experimental evidence tends to show that alcohol reduces fear in an approach-avoidance situation.Conger trained one group of rats to approach a food goal and, using aversive conditioning, trained another group to avoid electric shock.After an injection of alcohol the pull away from the shock was measurably weaker, while the pull toward the food was unchangeD、 The obvious troubles experienced by alcoholic persons appear to contradict the learning theory in the explanation of alcoholism. The discomfort, pain, and punishment they experience should presumably serve as a deterrent to drinking. The fact that alcoholic persons continue to drink in the face of family discord, loss of employment, illness, and other sequels of repeated bouts is explained by the proximity of the drive reduction to the consumption of alcohol; that is, alcohol has the immediate effect of reducing tension while the unpleasant consequences of drunken behavior come only later. The learning paradigm, therefore, favors the establishment and repetition of the resort to alcohol. In fact, the anxieties and feelings of guilt induced by the consequences of excessive alcohol ingestion may themselves become the signal for another bout of alcohol abuse. The way in which the clue for another bout could be the anxiety itself is explained by the process of stimulus generalization, conditions Or events occurring at the time of reinforcement tend to acquire the characteristics of stimuli. When alcohol is consumed in association with a state of anxiety or fear, the emotional state itself takes on the properties of a stimulus, thus triggering another drinking bout. The role of punishment is becoming increasingly important in formulating a cause of alcoholism based on the principles of learning theory. While punishment may serve to suppress a response, experiments have shown that in some cases it can serve as a reward and reinforce the behavior. Thus if the alcoholic person has learned to drink under conditions of both reward and punishment, either type of condition may precipitate renewed drinking. Ample experimental evidence supports the hypothesis that excessive alcohol consumption can be learneD、By gradually increasing the concentration of alcohol in drinking water, psychologists have been able to induce the ingestion of larger amounts of alcohol by an animal than would be normally consumeD、Other researchers have been able to achieve similar results by varying the schedule of reinforcement; that is, by requiring the animal to consume larger and larger amounts of the alcohol solutions before rewarding it. In this manner, animals learn to drink enough to become dependent on alcohol in terms of demonstrating withdrawal symptoms. |
